Are you saying Bill's mother was an "angel of death" nurse or that she was visited by the "angel of death". Actually, I think both are true.
Mama clinton killed at least one patient while a nurse. There was a major investigation into one suspicious death, which was squashed by a then Arkansas asst head of dept of health Jocelyn Elders, for which she was promoted to head the entire dept, and later as surgeon general, to the overall shock of the medical establishment.
